23 mile skydive!

I would like to know what figure they have supersonic as given that speed of sound changes with air density therefore altitude. Speed of sound at sea level is 761mph (340m/s) and at 120,000ft it is around 450mph (200m/s).

Here is a good pre jump (Feb) article titled Stratos Space Jump: Can You Fall Faster Than the Speed of Sound? that explains some of the physics http://www.wired.com/wiredscience/2...-can-you-fall-faster-than-the-speed-of-sound/

I think the better question to think is when isn't 833.9 mph faster than the speed of sound at any given altitude. :p

Judge, I am a parachute instructor and run a DZ in Shropshire (not too far from OCUK actually), if you think its easy and anyone can do it them PM me and I will train you, dispatch you, film your exit and post the video on here for all to see.

Your first jump would be from 3200ft and the parachute would be deployed for you automatically by a static line attached to the aircraft, so even easier than freefalling and having to deploy your own canopy.

Care to put your money where your mouth is?

How much is it to jump now?
Back in the 80s I did quite a few jumps at Halfpenny Green !! nr Wolverhampton! and they cost £7.
I stopped going because of the distance and when you got there the windsock would be horizontal to the floor.

Where do you jump at freefaller?

I don't anymore :( I haven't in many many years. :(

I trained at Langar when I was at uni (I went to Loughborough - so not far away). I was the chairman of the skydiving club there actually! :) That was over 10 years ago now. However I last jumped about 4-5 years ago.

I then have jumped all over the place, but mainly in the US (Perris Valey and Elsinore), Cyprus and France (Gap), as the weather is better, jumps are cheaper, and you can have more "fun" ;)

Nice to see you here mate :) I do miss it, but I just don't have the time anymore :(
 
Westie/Dimple, A static line parachute course costs £200, this includes all the ground training and your first jump which is from 3200ft, continuation jumps cost £45 which includes equipment hire and all revision/progression training. Back in the 80's you would have been jumping rounds which had a lower wind limit than modern rectangular Ram Air canopies, students can jump in winds of up to 15knts.

Guru without seeing you in person it would be very difficult to give you an answer. You need to be able to carry out your emergency procedure, which means pulling handles that are located on your chest as well as being able to reach up and grasp the steering toggles, To progress on to freefall you need to be able to reach behind you and pull the pilot chute out from a small pouch on the bottom of the container (like touching your right arse cheek)

If you can't bend your arms enough to do this it may be possible for you to do a tandem skydive if you can't do a solo.

Were you at Loughborough the same time as Ally Milne or Thea Follet?
 
Name rings a bell and we have some friends in common. :)

Milko, DM, Rich Wheatley were the main instructors when I was a student there. 1999-2002. I went to a few boogies in the summer after then, but then went to the states as part of the BCPA in 2003 and 2004. Then did my own thing after that.

Actually Dave Hickling did my Cat 8 jump!! :cool:
 
Forgive me for sounding dumb, but if he's jumping over New mexico surely from that altitude you could see the oceans and outlines of the actual continent?

Every image/video i've seen shows practcally the entire Earth being a desert landscape. No water/oceans in sight...

Well here is a photograph http://www.flickr.com/photos/nasamarshall/5051991898/ of SW U.S.A looking towards the pacific. It's taken from a height of, 380Km? on the I.S.S, the continental U.S.A is huuuuuge! Even from low earth orbit you can't see the entire outline.

Now Felix jumped from 10times lower down, 38Km I believe, so while he could see a long way he still wasn't high enough to see the oceans/outline of the continent.

But I agree, the camera angles we were treated to didn't really do justice to the view. I cannot wait to see full 1080 stuff from the capsule and suit. Should give a much better sense of how high he was.

Thanks for that :)
 
And to think he was 24 miles up but still not considered in space.

NASA put the start of space at 50 miles from the surface, its around that point where gravity from earth stops pulling you back. 62 Miles up and your not coming back without assistance. Wouldn't surprise me at all if Felix goes up again with a bigger balloon and tries for 35 miles or more :)

Ummm :) Gravity doesn't simply end, you don't reach a point and suddenly there is no gravity. How do you think the Moon is tied to the Earth? a big rope?

Why do you think NASA use rockets to get into orbit? They have to reach escape velocity in order to "fall" and miss the earth.

62 miles up is considered 'outer space' by the FAI, not sure how they would define just 'space' though.

Not bad considering it's born out of a fizzy drinks manufacturers marketing budget. I wish more companies adopted their approach

Don't put yourself under any illusion; this is just a different take on advertising. It happens to suit the company well as they do ground-breaking activities that require energy, energy from Red Bull obviously. You'll probably see pictures of Felix drinking Red Bull too.

4.7 billion cans sold worldwide per year means they have a pretty big budget for product placement. While, imo, this form of advertising is certainly better than billboards and TV ads, it can easily be argued that profit earned by Microsoft and then given to charities is an even better way of promoting a brand.
